The Opportunity
A long-term transformation programme is underway to modernise a Legacy application estate. We are looking for an experienced Software Engineer with strong Delphi knowledge to support the migration of a Windows-based PHP/Delphi system into a modern AWS environment.

Key components include:

• Migrating the existing MS SQL database to PostgreSQL
• Removing Windows dependencies and moving services to Linux
• Assessing and understanding Delphi components and redesigning/re-writing where required (potentially in C#/.NET)
• Supporting minimal Delphi UI work if needed
• Ensuring the new environment is scalable, stable, and cloud-optimised

Key Skills & Experience Required Essential

• Strong commercial experience with Delphi
• Experience analysing and modernising Legacy applications
• Ability to understand dependencies and propose modern alternatives
• Excellent communication and collaboration skills

Nice to Have

• Experience with Lazarus IDE
• Knowledge of WebSockets or REST APIs within Delphi
• PHP experience
• AWS/Docker exposure
• Experience with C# or .NET (for potential rewrites)

Why This Role?
You'll play a key part in a significant application modernisation programme running through to March 2026. The role provides autonomy, long-term stability, and interesting technical challenges focused on cloud migration and Legacy-to-modern reengineering.
